TREADLE MECHANISM FOR BED-LASTING MACHINES.

To all whom it may concern:

Be it known that I, HARRIE A. BALLARD, a citizen of the United States,and resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented. certain new and useful Improvements inTreadle Mechanisms for Bed-Lasting Machines, (Case A,) of which thefollowing is a specification.

In my copending application, Serial No. 198,420, filed March 16, 1904:,there is shown and described a bed lasting machine and treadle mechanismwhereby the operator by depressing the treadle causes a sequence ofmovements in the following order: (1) unlocking movement of a lockingdevice by which the wipers carriage is locked in working position; (2) amovement of the lasted shoe away from the wipers to relieve pressuresubsisting between the wipers and the pulled-over portions; (3)retractory movement of the carriage and wipers mounted thereon. Thepressure-relieving movement in said application is opposed by a springwhich acts upon the jack to furnish the necessary degree of pressurebetween the pulled-over portions of the upper and wipers in order to setor crease the pulledover portions. The said spring in order to properlyperform its function must be very stiff, and the degree of powerrequired to effect the pressure-relieving movement as between the wipersand the work must be of a corresponding degree. The results of sucharrangement, as shownby the work, are satisfactory; but so much efforton the part of the operator is required to relieve the pres- I sure thatI have devised improved mechanism for accomplishing substantially thesame results and in substantially the same manner with less effort onthe part of the operator, my improved machine being capable of morerapid operation in consequence of the ease with which it operates.

In order to point out the chief distinctions between the arrangement ofmechanism in my present improved machine and that in. the machine asshown and described in said copending application, I will give a briefanalysis of some of the characteristic features of both machines,referring to the machine shown in said copending application as thefirst machine and to the ma? Specification of Letters Patent.

chine of the present application as the present machine. I

In the first machine, the heel jack and toe ack were both movablevertically and lndependentlyof each other, and each was held upwardly byits own spring. In the present machine the heel jack and toe jack haveno vertical movement. In the first machine the wipers had no verticalmovement excepting such vertical movement as might be incidental toadjusting them relatively to their respective carriages. In the presentmachine the wipers have vertical movement other than and independent ofsuch vertical movement as may be incidental to adjusting them relativelyto their carriages. In the first machine the wiper carriages had novertical movement at all. In the present machine such carriages do havevertical movement. In the first machine the pressure of the wipers uponthe pulled-over portions was due entirely to the jack springshereinbefore mentioned, but in the present machine the pressure of thewipers upon the pulled-over portions is due primarily to gravity of thewiper mechanisms and their carriages and the movable supports upon whichthe carriages are arranged; and such pressure as may be due to gravitymay be amplified as desired by downward pressure on the treadle. Here iswhere the present machine embodies an arrangement of mechanism whichenables the operator to apply pressure to the pulledover portions tomeet the requirements of each individual shoe, the first machine beingincapable of varying the pressure of the wipers upon the pulled-overportions excepting such variations as might be caused by varying thecompression of the jack springs. In this respect, therefore, the presentmachine may be used with greater facility.

My present machine has other improvements which are hereinafterdescribed in detail.

Qf the accompanying drawings: Figure 1 represents a rear elevation of abed-lasting machine having treadle mechanism embodying the presentinvention. In this figure the wiper mechanisms are in working positionand their carriages are locked against retractory movement. Fig. 2represents a rear elevation, partly in section, of the toe end of themachine, the toe-wiper mechanism being in an intermediate position aswhen undergoing retractory movement. Fig. 3 is an elevation (frame insection) of the work-clamping device, the point of view being indicatedby line 33 of Fig. 1. Fig. 4 represents a plan view, partly in section,of the treadle mechanism Within the range of line 44 of F 1. Fig. 5represents an elevation of the heel end of the machine. Fig. 6represents a vertical section, on a larger scale, of the structurewithin the range of line 66 of Fig. 1. The position of the parts is thesame as that in Figs. 1 and 5. Fig. 7 represents a vertical sectionsimilar to Fig. 6 but showing the parts in another position, the treadleaccording to Fig. 7 being depressed, whereas according to Fig. 6 suchtreadle is in its initial or raised position. Fig. Srepresents a sectionthrough the structure intersected by line 8-8 of Fig. 7. Fig. 9represents a similar section through the same structure, showing theparts in a position corresponding to that of Fig. 6. Fig. 10 representsa vertical section from front to rear through the structure intersectedby line 101O of Fig. 1. Fig. 11 represents a front elevation of the heelack, the last and shoe being indicated by broken lines and the heel-andtoe-wipers being represented conventionally in overlapping position uponthe pulled-over portions of the upper, broken lines and arrowsindicating the general character of the paths of movement traversed bythe wipers when the latter are retracted.

The same reference characters indicate the same parts wherever theyoccur.

The main frame of the machine is indicated at 20. It is provided withvertical guides 21 at one end and similar vertical guides 21 at theother end, said guides coacting respectively with vertically movablesupports 22 and 22. These supports are in the form of brackets, and theyare formed with horizontal guides 23 and 23 respectively. A horizontallymovable carriage 24 is arranged to slide in guides 23, and a similarcarriage 24 is arranged to slide in guides 23. These carriages carry thetoe-wiping mechanism and heel-wiping mechanism respectively. Thetoe-wiping mechanism is indicated as a whole at 25, and the heel-wipingmechanism is indicated at 25.

The wiping mechanisms may be of any suitable structure and arrangement.The toe and heel-wipers are represented respectively at 26 and 26 inFig. 11, such representation being sufficient for the purposes of thisapplication. Referring again to Fig. 1, the main frame or base of thetoe-wiping mechanism is indicated at 27, and that of the heel-wipingmechanism at 27. These frames are arranged upon pivots 28, 28 carriedrespectively by the carriages 24, 24, each wiper mechanism being capableof tilting about its respective pivot for the purpose of adjusting thewipers relatively to the longitudinal plane of the toe and heel of theshoe. For the purpose of effecting such adjustment the toe-wipingmechanism is provided with an adjusting screw 29, and the heel-wipingmechanism is provided with an adjusting screw 29, said screws havingsuitable swivel connections with their respective carriages and wiperframes. Said frames are also provided with adjusting devices 30, 30whereby the wipers may be tilted laterally accord ing to the lateralplane of the toe and heel of the shoe. No additional disclosure of thelast mentioned adjusting means will be necessary for the purposes of thepresent application.

A shoe is indicated at 0:, and a last is indicated at a in Fig. 11. Theforepart of the last is indicated at a, and the heel-part at a A toejack is indicated at 31, and a heel jack is indicated at 31. The toejack is in the form of a sleeve nut and is ar- U ranged upon a screw 32which extends upwardly from a pedestal 33. The pedestal is arranged toslide on guides 34 formed upon the base 35. The base is afiixed to themain frame 20, and the guides 34 extend in lines substantially parallelto the longitudinal median line of the shoe. The heel jack 31 isarranged to slide on guides 34 formed upon the base 35, the guides 34extending transversely with relation to the guides 34.

Referring to Fig. 11, a last pin a is mounted upon a pivot pin a at theupper end of the heel jack, said pin extending transversely of thelongitudinal vertical plane of the shoe, so that the last in rockingabout the axis of the pin a will raise or lower the toe. A springfollower a arranged in a socket in the heel jack and backed by acompression spring a acts upon the last pin a to keep the toe of theshoe pressed down 1 wardly upon the toe jack.

The combination of jacks as described enables a right or left shoe to besupported so that the longitudinal median lines of its toe-part andheel-part may be alined with the longitudinal median lines of therespective wiping mechanisms. Thetoe jack may be set at any desiredpositions along its guides 34 according to the length of the shoe, andthe heel jack is adjustable transversely, the shoe being capable oftilting movement relatively to the heel jack independently of theadjustments of the jacks themselves. The height of the toe jack may bevaried by screwing the same up or down on the post 32.

A work clamp is indicated at 36. This clamp is in the form of a leafspring, and its ends are arranged to bear upon the insole of the shoeover the two jacks. The intermediate portion of the clamp is aflixed toan overhanging portion of a carrier 37. The carrier is arranged upon apivot member 38 which is carried by a sleeve'39. This sleeve is arrangedloosely upon a vertical rod 40 and is connectd to said rod by a pivotmember 41. The axis of 41 is transverse to the axis of 38. In order toprovide a universal connection between 37 and 40, and in order to enablethe sleeve 39 to tilt upon the pivot member 41, the hole in 39 throughwhich 40 extends is of a greater diameter than 40. The range of tiltingmovement of 39 relatively to 40, though limited, enables the clamp 36 totilt longitudinally according to the form of the bottom of the last. Theweight of the carrier 37 is mostly behind the pivot 38, and causes theclamp to tip automatically to the rear and beyond the shoe when liftedfrom the shoe, so that the shoe may be readily detached and another shoeattached. The portion 42 of the arm 37 is arranged to abut against thesleeve 39 to limit the rearward swinging of the clamp. The upper end ofrod 40 is arranged to slide in a stationary guide 43, and the lower endthereof is pivotally connected to a treadle lever 4-4 whose fulcrum isindicated at 45. A compression spring 46 is arranged to bear against ashoulder 47 of the rod'to raise the same, and the treadle 44 is arrangedto depress the rod against the force of the spring. A toothed sector 48is arranged to coact with the treadle to hold the same depressed, thetreadle being sufficiently loose upon its fulcrum 45 to permit a slightlateral movement of the treadle whereby it may be engaged with anddisengaged from the sector.

A toothed rack 50 is affixed to the carriage 24,. and a toothed rack 50is affixed to the carriage 24 These racks are enmeshed respectively withpinions 51, 51. These pinions are affixed to shafts 52, 52 (Figs. 5

. and 10), said shafts being mounted in bearings 53, 53 in thevertically movable supports 22, 22. These shafts are providedrespectively with hand wheels 54, 54 whereby the end-wiping mechanismsmay be moved independently of each other to working position. The handwheels have ratchets 55, 55, which are engaged by retaining pawls 56,56, said pawls being arranged to permit rotative movement of the handwheels in one direction to move the wiping mechanisms to workingposition, and to prevent retractory movement of the wiping mechanismsexcepting when they (pawls) are disengaged, as hereinafter described,from the ratchet wheels.

The pawls are affixed respectively to rockshafts 57, 57, and arenormally held against the ratchet wheels by tension springs 58, 58.Ailixed to the rear ends of the rockshafts are arms 59, 59. Rolls 60, 60at the free ends of said arms are arranged to coact with cams 61, 61,said cams being affixed to vertically movable slides 62, 62 111 suchmanner that when said slides rise, the cams actuate the arms 59, 59 todisengage the pawls from their respective ratchet wheels.

The slides 62, 62 in addition to retracting the locking pawls as justexplained, serve the additional purpose of transmitting motion from atreadle, hereinafter described, to the carriages 24, 24 to retract saidcarriages from working position. The said slides are carriedrespectively by the supports 22, 22, but are movable relatively to saidsupports. The mounting of the two slides .is similar, and it will besufficient to describe one of them, such mounting being shown in sectionby Fig. 10. The slide is formed with slots 63 whichare occupied bybushings 64. These bushings are mounted upon screw-studs 65. Slide .62is provided with a vertical series ,of teeth 66, and slide 62 isprovided with a similar series of teeth 66. Lifting dogs 67, 67 arearranged to coactrespectively with the two sets of teeth. These dogs aremounted in tilting holders 68, 68, said holders being arranged uponpivots 69, 69 carried by lifting rods 7 O, 70. Said rods are arranged toslide vertically in guides 71, 71 on the main frame 20. Links 72, 72connect the lower ends of the rods with treadles 73, 73. The fulcra ofsaid treadles are in line with each other and are. indicated at 74(Figs. 2, 6 and 7) and 74 The rear ends of treadles 7 3, 7 3

are connected. by a tie-bar 75 whereby said treadles are rigidly unitedand are, to all intents and purposes, a single actuator, although theirforward ends are separated and the operator may depress either one,according to which is more convenient, with the same result.

Thelifting dogs 67, 67 are moved into engagement with their respectiveteeth by tension springs 76, 76, but are retracted, when they descend,by stationary pins 77. 77 the holders 68 being provided with camsurfaces 7 8, 7 8' arranged to engage said pins for the purpose stated.

From the foregoing description it may be seen that depressing theforward end of treadle 73 or 73 will lift both of the rods 70, 7 0,disengage the holders 68, 68 from pins 77, 77, lift slides 62, 62. andretractlocking pawls 56, 56 from their respective ratchet wheels. I willnow describe the mechanism by which. this same upward movement of the sldes 62, 62 effects ii'etractory movement of the wiper carriages 24, 24from working position.

A dog 80 is arranged upon a pivot stud 81 carried by carriage 24, and asimilar dog; 80 is similarly arranged upon a pivot stud 81 carried bycarriage 24. These dogs normally hang in the positions shown by Fig. l,the carriages being provided with stop pins 82, 82 arranged to preventthe lower ends of the dogs from swinging to a vertical line intersectingthe axes of the supporting pivots. In other words, the stop pins keepthe lower ends of the dogs away from the vertical center of the pivots,the angular position of the dogs being capable of variation withincertain limits, as will be understood after further description. Thevertically movable slide 62 has in its upper edge a horizontal series ofteeth 83, and the slide 62 has a similar series of teeth 88. The lowerends of the dogs are pointed and adapted to enter the notches betweenthe teeth of their respective slides. When the slides are in theirnormal position, as shown by Fig. 1, the teeth just described are asuliicient distance below the dogs to clear the latter so that the dogsmay move freely when the wiper carriages are moved through the agency ofthe hand wheels 54, 54: As shown by Fig. 1, the slides 82, 62' areresting upon supporting abutments 84, 84, said abutments being formedupon or afliXed to the supports 22, 22.

Assuming that it is desired to retract the end-wiping mechanismshorizontally from the working position as shown by Fig. 1, the operatordepresses one of the treadles 73, 73, and the first part of suchmovement results in retracting the locking pawls 56, 56 from lookingposition as hereinbefore explained. The upward movement of the slides62, 62 necessary to cause such movement of the locking pawls takes upthe clearance between the teeth 83, 83 and the dogs 80, and continuedupward movement of the slides is transmitted by the dogs to thecarriages 24, 24, which are lifted bodily enough to clear the wipersfrom the pulledover portions :0 of the shoe (Fig. 11). Upward movementof the carriages 24, 24 is transmitted to the supports 22, 22 throughthe tongue-and-groove guides 23, 23 which connect the carriages withtheir respective supports. The lower ends of the dogs 80, 80 being offcenter as hereinbefore explained, the angular relation of the dogs withrespect to the direction of the force of gravity, although initiallyslight, is not sufli-- cient to sustain the weight of the supports 22,22 and the loads imposed thereupon; and accordingly the initially slighthorizontal thrust, due to the initial angular position of the dogs,overcomes the inertia of the carriages 24-, 2d, and the carriagesthereupon move outwardly, that is, away from each other; and as they doso, the angular positions of the dogs 80, 80 grow more pronounced,increasing the horizontal thrust and decreasing the rcrtical thrust, sothat the supports 22 and 22 settle down to their initial positionsalmost immediately, and

continued upward movement of the slides 62.

62 causes only further horizontal movement of the carrlages.

Referring to Fig. 11, broken line 6 represents the path traversed by thetoeeach case is upward, the rise being due to the inertia of thehorizontally movable carriage and mechanism carried thereby. The highestpoint in each curve corresponds to that stage when such inertia has beenovercome and the carriage is moving horizontally at a rate sufiicient toneutralize the up ward tendency, all such parts as are subject tosettling by gravity doing so after the high point has been reached, andthe remainder of the retractory movement being compounded withdescending movement of the carriages and their supports.

Under some conditions, as when the ma chine is not in use, the weightof. the supports 22, 22 is sustained by links 85, 85.

The upper ends of said links are connected with the supports by pivotstuds 86, 86, and the lower ends are connected by pivot studs 87 87 toarms or levers 88, 88. These links are made up of a plurality of piecesincluding turnbuckles 89, 89 whereby the normal or initial positions ofthe supports as to vertical movement may be varied by adjustment. Theturnbuckles are provided with hand wheels 90, 90. The levers 88, 88 areaiiixed to rockshafts 91, 91 mounted in suitable hearings in main frame20. (See Fig. 4.) Treadles are provided for operating the levers 88,88,the treadle for 88, as shown by Fig. 4, being formed integrally withsaid lever. The treadle for 88 has a foot-engaging portion 92 arrangedat one side of the center, and a foot-engaging portion 93 arranged atthe opposite side of the center. In like manner the treadle for 88 isprovided with a foot-engaging portion 92 at one side of the center, andwith a foot-engaging portion 93 at the opposite side of the center. Whenthe portions 92, 92 are depressed, the wiper mechanisms are raised, aswhen moving the wipers into engagement with the work, the turnbuckles 89being preferably adjusted so as to set the under surfaces of the wipersslightly below the positions which they would occupy when bearing uponthe pulled-over portions of the upper. The operator, therefore, inmoving the wipers to the work, depresses the portions 92, 92 as may benecessary in order to carry the wipers over the pulled-over portions. Itfollows, therefore, that when the wipers overlap the pulled-overportions as shown by Fig. 11, the entire weight of the wiper mechanisms,their carriages, and

inhabits the supports 22, 22 is sustained by the pulled-over portions;If in the judgment of the operator the. pressure due to the force ofgravity is not sufficient, as for example when operating upon leatherwhich is relatively thick and stiff, he may supplement such pressure bystepping upon the portions 93, 93 of the treadles. -When suchsupplemental pressure is discontinued the q initial pressure due togravity remains, and

tions is not enough, however, to enable the treadles and connect-edparts to be strained to the breaking point.

Referring again to Fig. 11, although the pressure-relieving movement ofthe wipers may be caused by inertia of the wiping mechanisms and theircarriages opposing horizontal movement, as hereinb'efore 'eX- plained,such inertia may not be suflicient when the treadles 73, 73 aredepressed too slowly; and, in order to guard against failure of suchmovement, I have provided mechanism which will act positively to causethe desired upward movement of the wlpers. The mechanism for thispurpose is shown by Figs. 2, 6, 7, 8 and 9, in which said mechanism isapplied to the toe-end of the machine. Such mechanism is duplicated forthe heel-end of the machine, but for the present purpose it will besufficient to refer only to the one mechanism as shown by Figs. 6 to 9.

Fig. 6' shows treadle 73 and the other parts in their normal position,as when the wipers are resting upon the pulled-over portions of theupper. A lifting dog 94 is arranged upon a pivot 95. This pivot iscarried by a tilting member 96 which in turn is arranged upon a pivot 97carried by the treadle lever 7 3. The member 96 may rock relatively tothe treadle lever, and the dog 94 may rock relatively to the member 96.The pivot 97 is so arranged in relation to the fulcrum 74 of'the leveras to cross the vertical center of said fulcrum when the treadle isdepressed, the first part (substantially half, as shown) of the downwardmovement of the treadle causes upward movement of pivot 97 and acorresponding upward movement of dog 94. WVhenjthe treadle 73 is in itsinitial position, as shown" by Fig. 6,-the dog 94 rests upon a stop 98(Fig. 9) aflixed to the main frame 20 of the machine. Said stop as shownis in the form of a setscrew and is adjustable. 94 is so formed as to betilted automatically by the force of gravity toward a series of teeth 99when the dog is lifted away from the stop 98. The teeth 99'are affixedto the support 22. It is apparent, therefore, that during substantiallyone-half of the entire downward movement of the treadle 73 the liftingdog 94 will rise and will engage the tooth which is next above it. Theteeth are sufiiciently close to each other to insure a substantialupward movement of the support 22 between the time when the dog94reaches tooth-engaging position and the time when the pivot 97 reachesthe vertical center of the fulcrum 74. The support 22, carriage 24, andwiping mechanism thereon, are thereby raised positively should thedownward movement of the treadle be too slow to utilize horizontalinertia of the carriage and wiping mechanism for the purpose explained.The lifting dog 94 does not;

take the place of the lifting dog 67 but is used in conjunction with thelatter, dog 94 The dog I positively raising the support 22 while dog 67is positively raising the slide 62. There is one thing to be borne inmind in connection with this combination of lifting dogs, and that isthat after the pivot 97 has passed the vertical center of the fulcrum 74the lifting dog 94 descends, permitting a corresponding descent of thesupport 22; but the lifting dog 67 continues to rise until the treadle"has reached its lowest position. From this it follows that thehorizontal retractory movement of the wipers will occur after thevertical pressure-relieving movement has been effected by the liftingdog 94. The return movement of the dog 94, which occurs when theoperator takes his foot from thetreadle 73, is of no consequence; but itmay be well, nevertheless, to describe whathappens at that time. Theweight of the parts attached to the treadles 73, 73

behind the fulcra 74, 7 4 is sufficient to auto matically raise theforward ends of the treadles when the latter are released after beingdepressed. During the return movement of the treadles to the positionshown by Fig. 6, the slide 62 descends and the pivot 97 is carried tothe rear across the vertical center of the fulcrum 74 and causes upwardmovement of the support 22, carriage 24 and wiper mechanismcoextensively with the pressure-relieving movement previously effected.The lifting dog 94 in returning to its initial position encounters thestop 98 and is thereby automatically disengaged from the series of teeth99, thereby leaving the support 22 free to be manipulated by the doubletreadle 92, 93. It should also be borne in 'mlnd lie lifting dog 67returns to its initial position its cam surface 78 rides upon thestationary pin 77 to retract 67 from the series of teeth 66.Simultaneously with such retraction of the .dog 67 the cam 61 releasesthe arm 59, and the locking pawl 56 is thereupon set against the ratchetwheel 55 in consequence of the action of spring 58.
